TH ERMOM ETER-FRAME.

SPECIFICATION forming'part of Letters Patent No. 496,995, dated May 9,1893.

" Application filed May 11, 1892- To all whom it may concern:

Be it known that I, ARCHER II. BURR, of Omaha, in the county of Douglasand State of Nebraska, have invented certain useful Improvements inThermometer-Frames and I do hereby declare that the following is a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification.

This invention relates to a new and novel thermometer frame, and is moreparticularly adapted to be used with those thermometers employed inconnection with incubators.

In the accompanying drawings, Figure 1 shows a top view of mythermometer frame. Fig. 2 is an end elevation thereof. Fig. 8 is aperspective view of the device as completed. Fig. 4 shows a top view ofasheet metal blank, in which the base blank and web are cut in one piece.Fig. 5 shows a modificationwhere I employ a quadrilateral shaped blank,which is erimped into proper shape, as shown by the end view, Fig. 6.

The object of my invention is, to provide a simple thermometer frame, soconstructed that the thermometer may be positioned immediately above theeggs, and held, so that a read- .ing may be taken, without disturbingthe thermometer or opening the incubator.

In theaccompanyingdrawings,I have shown an elongated sheet metal baseplate A, which is preferably rounded at each end and narrows toward thecenter and is provided with a bulb opening a near one end, and thetransverse vertical web B, provided with the semicircular bulb openingI), as clearly shown in Fig. at.

The base plate A and the web B are preferably stamped out of one pieceof metal,the two parts being united by the narrow neck D. The web inbeing secured to the base plate A is simply bent at right angles to theplane of the base plate, and then turned back and upon the upper portionof said base plate and thus secured by any suitable means. The neck Dmay be readily curved and bent, so as to permit the web being carriedover and upon the plate.

The base plate A is preferably slightly Serial No. 432,685. (No model.)

curved laterally, so as to conform to the shape of the eggs, upon whichthe frame is adapted to be placed, the web B, being soldered or securedto a base plate by any suitable means. To this web is secured thethermometer O in an inclined position, so as to lessen the chances ofthe mercurial column parting, as might be the case, when the thermometerrests perfectly horizontal. The thermometer issecured to the web by anysuitable means.

In the drawings I have shown two sheet metal blanks, but if desired thestandard could be made of any other suitable material.

In Fig. 5, the blank is orimped into shape and made of one continuoussheet.

In addition to holding the thermometer in proper position, the blankacts as a guard in protecting the thermometer, as the latter is heldwithin the angle, formed by the two blanks.

Having thus described my said invention, what I claim as new, and desireto secure by United States Letters Patent, is

1. As a new article of manufacture, a thermometer frame blank,comprising a narrow base plate rounded at each end and narrowing towardthe center and laterally slightly curved, and secured to a web, said webforming part of and being secured to said base plate by means of aconnecting neck, a circular bulb opening within said base plate and acoinciding semi-circular bulb opening within said web, said web beingadapted to be turned back and upon said base plate and secured by anysuitable means, so as to form the thermometer frame, substantially asshown.

2. Asanew article of manufacture, the blank hereinbefore describedcomprising the laterally curved base plate A, rounded at each end andnarrowing toward the center and connected by means of the neck D to theweb B, said plate A being provided at the one end with a circularopening, and the web B at the same end with a registering semi-circularopening, all substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ARCHER H. BURR.
